Distinct Determinants of Hospitalisation and In-Hospital Mortality After Acute Stroke: Insights into Stroke–Heart Syndrome (SHS-PARTICLES Study)

Background/Objectives: Stroke–heart syndrome (SHS) involves myocardial injury, cardiac dysfunction, and arrhythmias after acute stroke, playing a key role in prognosis. Most evidence comes from acute ischaemic stroke (IS), while cardiac involvement after haemorrhagic stroke (HS) is less understood. Additionally, the prognostic roles of cardiac biomarkers, neurological severity, and cardiac systolic function on early outcomes are not well defined.
